Empire builders taking some from answer (6)
I believe the answer is:
romans
'empire builders' is the definition.
(I've seen this before)
'some from answer' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ROMANS' can be found hidden inside 'from answer'.
'taking' acts as a link.
(Other definitions for romans that I've seen before include "Citizens of Italian capital" , "Mark Antony's countrymen?" , "New Testament book" , "Empire builders" , "Ancient Italians" .)
